IMPROVEMENT IN ATOMIZERS.

Specification formingpart of Letters Patent N 0. 176,31 l, dated April 18, 1876; application filed March 3, 1876.

To all whom it may concern.-

.Be it known that I, THOMAS J. HoLMEs, of Boston, in' the county of Suffolk and State of Massachusetts, have invented certain Improvements in Atomizers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is an elevation of an atomizer constructed in accordance with my invention. Fig. 2 is a vertical section through the center of the same.

My invention relates to certain improvements in atomizers; and consists in the arrangement of the air-valve on the opposite side of the central portion to that in which I the discharge-orifice is located, whereby the necessity of providing the air-bulb with a valve and the objections incident thereto are avoided.

My ivention also consists in the combination of av hollow screw-shank with the central portion, the bulb-support, and the valvesupport, all cast in the same piece, by which construction the stopper is securely held in place, and when worn out can be readily removed from the screw-shank and replaced by a new one.

My invention also consists in providing the central portion with ascrewthread for the reception of the upperl end of the liquid-tube, in combination with thehollow stopper-screw, which construction admits of the ready connection and removal of the liquid-tube.

To enable others skilled in the art tounderstand and use my invention, I will proceed to describe the manner in which I have carried it out.

In the said drawings, A represents a bottle, in the mouth of which is fitted the stopper a, provided with a central hole extending vertically through it for the passage of a screwshank, b, projecting down from the under side of a metallic cap, 0, formed at the base of a central portion, 01, at the top of which is formed the cap-shaped support a, to which the airbulb B is secured by means of a hollow screw,

f, which communicates with a vertical passage, h, leading into the horizontal air-passage i, at one end of which is located the atomizing point or dlscharge-oritice k, and at the other end-the valve 1, through which the air for supplying the bulb is admitted, the valve being situated within the part 1" of the central portion 61 which forms the valve-support. The bottom of the central portion 01 is provided with a screw-thread, into which is screwed the upper end of the tube m, through which the liquidin the bottle is forced into a horizontal passage, n, thence through a channel formed by cutting away the under side of the screw P to the atomizing-point or dischargeorifice k, where it is dissipated into spray by the current of air passing through the passage '5, which creates a vacuum at this point, and thus causes the liquid to be forced up the tube m in a well-known manner.

The hollow screw-shank b, bulb-support e, and central portion 61 between them are cast in a single piece, whereby the construction is simplified, the cost reduced, and the liability to get out of order is diminished.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The arrangement of the air-valve Z on the opposite side of the central portion d to that in which the discharge-orifice is located, substantially as and for the purpose set forth.

2. The hollow screw-shank b, in combination with the central portion 01, bulb-support e, and valve-support 1", all cast in the same piece, substantially as and for the purpose described.

3, The central portion d, provided with a screw-thread for the reception of the upper end of the liquid tube m, in combination with the hollow screw-shank b, substantially as and for the purpose described.

Witness my hand this 24th day of February, 1876.

THOS. J. HOLMES.

In presence of N. W. STEARNS, W. J. CAMBRIDGE.
